Description

TELEPHONE MOBILE A COUVERCLE ARTICULE ET CONTACTS TOURNANTS MOBILE PHONE WITH ARTICULATED COVER AND ROTATING CONTACTS
La présente invention concerne un téléphone mobile comprenant un boîtier renfermant un circuit électrique et portant un couvercle fixé de façon articulée à ce boîtier et comportant un microphone.The present invention relates to a mobile telephone comprising a housing containing an electrical circuit and carrying a cover hingedly attached to this housing and comprising a microphone.
On a décrit dans la demande de brevet français n°96 12 305 du 9 Octobre 1996 au nom de la demanderesse, un téléphone mobile du type ci-dessus dans lequel des contacts tournants sont incorporés dans l'une des deux articulations reliant le couvercle au boîtier, pour établir des connexions électriques entre le circuit électrique et le microphone. On connaît selon le WO 96 21 988 un téléphone mobile comprenant un boîtier renfermant un circuit électrique et portant un couvercle fixé de façon articulée à ce boîtier et comportant un microphone, des contacts tournants étant incorporés dans l'une des deux articulations reliant le couvercle au boîtier pour établir des connexions électriques entre le circuit électrique et le microphone. L'une des articulations du boîtier au couvercle comprend deux contacts solidaires du boîtier comportant chacun un bras de contact, les extrémités des deux bras de contact prenant appui élastiquement sur deux plages conductrices séparées par une matière isolante et incorporées dans la partie de l'articulation du couvercle. Ainsi lors de la rotation du couvercle, les extrémités des deux bras de contact décrivent sur les plages conductrices deux trajets circulaires .There has been described in French patent application No. 96 12 305 of October 9, 1996 in the name of the applicant, a mobile telephone of the above type in which rotary contacts are incorporated in one of the two articulations connecting the cover to the housing, to establish electrical connections between the electrical circuit and the microphone. According to WO 96 21 988, a mobile telephone is known comprising a box containing an electrical circuit and carrying a cover hingedly attached to this box and comprising a microphone, rotary contacts being incorporated in one of the two articulations connecting the cover to the housing for making electrical connections between the electrical circuit and the microphone. One of the articulations of the housing to the cover comprises two contacts integral with the housing each comprising a contact arm, the ends of the two contact arms bearing elastically on two conductive pads separated by an insulating material and incorporated in the part of the articulation of the cover. Thus when the cover is rotated, the ends of the two contact arms describe on the conductive pads two circular paths.
Dans cette réalisation, les deux contacts prennent appui sur les pistes conductrices transversalement par rapport à l'axe de rotation de l'articulation. Cette disposition ne permet pas de garantir une pression de contact adéquate uniforme des bras sur les pistes quelle que soit la position angulaire du couvercle par rapport au boîtier.In this embodiment, the two contacts bear on the conductive tracks transversely to the axis of rotation of the joint. This provision does not guarantee an adequate uniform contact pressure of the arms on the tracks regardless of the angular position of the cover relative to the housing.
Le but de la présente invention est d'apporter des perfectionnements aux téléphones mobiles connus ayant pour but d'augmenter la fiabilité de la connexion électrique réalisée par les contacts tournants et de faciliter la production à l'échelle industrielle de ceux-ci .The object of the present invention is to provide improvements to known mobile telephones, the aim of which is to increase the reliability of the electrical connection produced by the rotary contacts and to facilitate their production on an industrial scale.
Suivant l'invention, ce téléphone mobile est caractérisé en ce que les deux bras de contact et les deux plages conductrices sont disposés de part et d'autre de l'axe de l'articulation.According to the invention, this mobile phone is characterized in that the two contact arms and the two conductive pads are arranged on either side of the axis of the joint.
Lors de la rotation du couvercle, les deux bras de contact frottent sur les plages conductrices . Ce frottement produit un effet d'auto-nettoyage permettant d'assurer une grande fiabilité de la connexion électrique .When the cover is rotated, the two contact arms rub on the conductive pads. This friction produces a self-cleaning effect which ensures high reliability of the electrical connection.
De plus, la disposition des bras de contact et des plages conductrices de part et d'autre de l'axe de rotation de l'articulation permet aux bras de contact d'appliquer sur les plages conductrices une pression dirigée suivant l'axe ci-dessus qui est répartie de part et d'autre de cet axe. Ainsi, cette pression de contact est régulière et homogène quelle que soit la position angulaire du couvercle par rapport au boîtier.In addition, the arrangement of the contact arms and conductive pads on either side of the axis of rotation of the joint allows the contact arms to apply pressure on the conductive pads directed along the axis ci- above which is distributed on either side of this axis. Thus, this contact pressure is regular and homogeneous whatever the angular position of the cover relative to the housing.
De préférence, les deux bras de contact et les deux plages de contact sont symétriques par rapport à l'axe de l'articulation.Preferably, the two contact arms and the two contact pads are symmetrical with respect to the axis of the joint.
La position des plages conductrices par rapport aux bras de contact est telle que lorsque le couvercle est rabattu sur le boîtier, l'extrémité de l'un des bras de contact prend appui sur la matière isolante comprise entre les deux plages conductrices.The position of the conductive pads with respect to the contact arms is such that when the cover is folded over the housing, the end of one of the contact arms is supported on the insulating material between the two conductive pads.
Ainsi, lorsque le couvercle est fermé, aucun courant électrique ne circule entre le circuit électrique du boîtier et le microphone porté par le couvercle .Thus, when the cover is closed, no electric current flows between the circuit box and the microphone carried by the cover.
On évite ainsi une usure prématurée de la pile alimentant l'appareil lorsqu'il n'est pas utilisé. Selon une version préférée de l'invention, chaque contact est constitué par une pièce découpée dans une feuille de métal et comprend trois bras, l'un constituant le bras de contact, le deuxième comportant une extrémité emboîtée dans un bloc en matière isolante incorporée dans l'articulation du boîtier et le troisième bras situé à l'opposé du premier étant en contact par son extrémité avec le circuit électrique du boîtier.This prevents premature wear of the battery supplying the device when it is not in use. According to a preferred version of the invention, each contact consists of a piece cut from a sheet of metal and comprises three arms, one constituting the contact arm, the second comprising one end fitted into a block of insulating material incorporated in the joint of the housing and the third arm located opposite the first being in contact at its end with the electrical circuit of the housing.
Un tel mode de réalisation permet de réduire le nombre de pièces, de faciliter le montage et d'augmenter la fiabilité.Such an embodiment makes it possible to reduce the number of parts, to facilitate assembly and to increase reliability.
Pour les mêmes raisons, de préférence, les plages conductrices sont constituées chacune par une pièce découpée dans une feuille métallique et pliée, fixée sur un bloc en matière isolante incorporé dans l'articulation du couvercle.For the same reasons, preferably, the conductive pads each consist of a piece cut from a metal sheet and folded, fixed on a block of insulating material incorporated in the joint of the cover.
Selon une version avantageuse de l'invention, l'articulation du boîtier comprend une surface tronconique centrée sur l'axe de l'articulation dans laquelle s'emboîte une surface tronconique complémentaire de l'articulation du couvercle.According to an advantageous version of the invention, the articulation of the housing comprises a frustoconical surface centered on the axis of the articulation into which a frustoconical surface complementary to the articulation of the cover fits.
Cet emboîtement permet un centrage parfait des deux parties de l'articulation et en particulier des bras de contact par rapport aux plages conductrices . De préférence, l'autre articulation du boîtier au couvercle comprend un ressort mettant en appui les deux surfaces tronconiques complémentaires précitées, un certain jeu étant pratiqué entre les deux parties de ladite autre articulation pour permettre l'enlèvement du couvercle par compression du ressort et déboîtement des deux surfaces tronconiques complémentaires. Il est ainsi facile de démonter le couvercle pour le remplacer par un couvercle neuf.This interlocking allows perfect centering of the two parts of the joint and in particular of the contact arms with respect to the conductive pads. Preferably, the other articulation of the housing to the cover comprises a spring bearing the two aforementioned complementary frustoconical surfaces, a certain clearance being practiced between the two parts of said other articulation to allow the removal of the cover by compression of the spring and disengagement of the two complementary frustoconical surfaces. It is thus easy to dismantle the cover to replace it with a new cover.
Selon une version particulière de l'invention, l'autre articulation comprend deux surfaces en contact l'une sur l'autre sous l'action d'un ressort, l'une de ces surfaces comprenant plusieurs reliefs angulaireirtent décalés engagés dans des creux formés dans l'autre surface de façon à définir plusieurs positions angulaires du couvercle par rapport au boîtier. On peut ainsi définir avec précision, la position de fermeture complète du couvercle, et celle située à la position optimale d'utilisation.According to a particular version of the invention, the other articulation comprises two surfaces in contact with one another under the action of a spring, one of these surfaces comprising several angularly offset reliefs engaged in formed recesses in the other surface so as to define several angular positions of the cover relative to the housing. It is thus possible to define with precision, the position of complete closure of the cover, and that located at the optimal position of use.
De préférence, chaque relief comprend un sommet, une rampe montante et une rampe descendante disposées symétriquement de part et d'autre de ce sommet.Preferably, each relief comprises a vertex, an ascending ramp and a descending ramp arranged symmetrically on either side of this vertex.
Les rampes montante et descendante des reliefs permettent une rotation facile du couvercle, tout en assurant un positionnement précis de celui-ci dans différentes positions privilégiées. De préférence également, les deux surfaces en contact comprennent trois reliefs et trois creux décalés l'un de l'autre suivant un angle de 120°.The rising and falling ramps of the reliefs allow easy rotation of the cover, while ensuring precise positioning of the latter in different preferred positions. Also preferably, the two surfaces in contact include three reliefs and three depressions offset from each other at an angle of 120 °.
Ce décalage angulaire de 120°, permet de basculer le couvercle entre une position fermée et une position décalée de 120° dans laquelle le microphone du couvercle occupe un emplacement optimal pour l'utilisation du téléphone.This angular offset of 120 ° makes it possible to switch the cover between a closed position and a position offset by 120 ° in which the microphone of the cover occupies an optimal location for using the telephone.
De préférence, les deux surfaces en contact peuvent être déboîtées l'une de l'autre. II est ainsi facile d'enlever le couvercle pour le remplacer par un couvercle neuf.Preferably, the two surfaces in contact can be dislocated from one another. It is thus easy to remove the cover to replace it with a new cover.
Selon une version avantageuse de l'invention, les reliefs et les creux coopèrent les uns avec les autres pour définir une position dans laquelle le couvercle est complètement rabattu sur le boîtier et où les contacts tournants incorporés dans l'autre articulation n'établissent pas la liaison électrique entre le circuit électrique et le microphone à la position ci-dessus et jusqu'à une première position angulaire du couvercle et établissent cette liaison électrique lorsque la position angulaire du couvercle est située au-delà de la première position ci-dessus.According to an advantageous version of the invention, the reliefs and the hollows cooperate with each other to define a position in which the cover is completely folded down on the housing and where the rotary contacts incorporated in the other articulation do not establish the electrical connection between the electrical circuit and the microphone at the above position and up to a first angular position of the cover and establish this electrical connection when the angular position of the cover is located beyond the first position above.
D'autres particularités et avantages de l'invention apparaîtront encore dans la description ci- après . Aux dessins annexés donnés à titre d'exemples non limitatifs: la figure 1 est une vue en perspective à échelle agrandie de l'articulation du boîtier d'un téléphone mobile selon l'invention, montrant les bras des contacts tournants incorporés dans cette articulation,Other features and advantages of the invention will become apparent in the description below.

Dans la réalisation des figures 1 à 4, le téléphone mobile comprend un boîtier 1 renfermant un circuit électrique 2 et portant un couvercle 3 fixé de façon articulée à ce boîtier 1 et comportant un microphone (non représenté) . Des contacts tournants sont incorporés dans l'une 4a, 4b des deux articulations reliant le couvercle 3 au boîtier 1, pour établir des connexions électriques entre le circuit électrique 2 et le microphone. Conformément à l'invention, l'articulation 4b du boîtier 1 au couvercle 3 comprend deux contacts solidaires du boîtier 1 comportant chacun un bras de contact 5.In the embodiment of FIGS. 1 to 4, the mobile telephone comprises a box 1 containing an electrical circuit 2 and carrying a cover 3 fixed in an articulated manner to this box 1 and comprising a microphone (not shown). Rotating contacts are incorporated in one 4a, 4b of the two articulations connecting the cover 3 to the housing 1, to establish electrical connections between the electrical circuit 2 and the microphone. In accordance with the invention, the articulation 4b of the housing 1 to the cover 3 comprises two contacts integral with the housing 1 each comprising a contact arm 5.
Les extrémités 5a des deux bras de contact 5 prennent appui élastiquement sur deux plages conductrices 6 séparées par une matière isolante 7 et incorporées dans la partie 4b de l'articulation du couvercle 3. De ce fait, lors de la rotation du couvercle 3, les extrémités 5a des deux bras de contact 5 décrivent sur les plages conductrices 6 deux trajets circulaires.The ends 5a of the two contact arms 5 bear elastically on two conductive pads 6 separated by an insulating material 7 and incorporated in the part 4b of the articulation of the cover 3. Therefore, during the rotation of the cover 3, the ends 5a of the two contact arms 5 describe on the conductive pads 6 two circular paths.
Dans l'exemple représenté, les deux bras de contact 5a et les deux plages de contact 6 sont symétriques par rapport à l'axe X-X' de l'articulation 4a, 4b.In the example shown, the two contact arms 5a and the two contact pads 6 are symmetrical with respect to the axis XX ′ of the articulation 4a, 4b.
La position des plages conductrices 6 par rapport aux bras de contact 5 est telle que lorsque le couvercle 3 est rabattu sur le boîtier 1, l'extrémité 5a de l'un des bras de contact 5 prend appui sur la matière isolante 7 comprise entre les deux plages conductrices 6, comme indiqué sur les figures 6 et 8. Comme on le voit sur les figures 1 et 4, chaque contact est constitué par une pièce 8 découpée dans une feuille de métal élastique et bon conducteur et comprend trois bras 5, 9, 10. L'un d'eux constitue le bras de contact 5, le deuxième 9 comporte une extrémité 9a emboîtée dans un bloc 11 en matière isolante incorporée dans l'articulation 4a du boîtier 1 et le troisième bras 10 situé à l'opposé du premier est en contact par son extrémité 10a avec la carte de circuit imprimé constituant le circuit électrique 2 du boîtier 1.The position of the conductive pads 6 relative to the contact arms 5 is such that when the cover 3 is folded over the housing 1, the end 5a of one of the contact arms 5 is supported on the insulating material 7 between the two conductive pads 6, as indicated in FIGS. 6 and 8. As seen in Figures 1 and 4, each contact consists of a piece 8 cut from a sheet of elastic metal and good conductor and comprises three arms 5, 9, 10. One of them constitutes the contact arm 5, the second 9 has an end 9a fitted into a block 11 of insulating material incorporated in the joint 4a of the housing 1 and the third arm 10 located opposite the first is in contact at its end 10a with the circuit board printed circuit constituting the electrical circuit 2 of the housing 1.
Comme indiqué notamment par la figure 7, les plages conductrices 6 sont constituées chacune par une pièce découpée dans une feuille pliée, en métal bon conducteur, fixée sur un bloc 12 (voir figures 2 et 5) en matière isolante incorporé dans l'articulation 4b du couvercle 3.As indicated in particular in FIG. 7, the conductive pads 6 each consist of a piece cut from a folded sheet, of good conductive metal, fixed on a block 12 (see FIGS. 2 and 5) made of insulating material incorporated in the joint 4b cover 3.
Comme montré sur les figures 2 et 5, les deux plages conductrices 6 sont appliquées sur une face terminale du bloc 12 en matière isolante et chaque plage 6 est reliée à une patte 13 perpendiculaire à la plage et s ' étendant à l'intérieur du bloc 12 en matière isolante; chaque patte 13 est reliée électriquementAs shown in FIGS. 2 and 5, the two conductive pads 6 are applied to an end face of the block 12 made of insulating material and each pad 6 is connected to a tab 13 perpendicular to the pad and extending inside the block 12 in insulating material; each leg 13 is electrically connected
(voir figures 3 et 4) à un conducteur 14 relié au microphone. A cet effet, l'extrémité 15 de chaque patte 13 est conformée pour pouvoir dénuder l'isolant du conducteur 14.(see Figures 3 and 4) to a conductor 14 connected to the microphone. To this end, the end 15 of each tab 13 is shaped so as to be able to strip the insulation of the conductor 14.
Par ailleurs, les deux plages conductrices 6 sont séparées, d'une part, par une zone centrale 7 (voir figure 2) en matière isolante dont la surface fait légèrement saillie par rapport aux plages conductrices 6 et, d'autre part, par deux cavités 15a, 15b, diamétralement opposées.Furthermore, the two conductive pads 6 are separated, on the one hand, by a central zone 7 (see FIG. 2) of insulating material, the surface of which protrudes slightly from the conductive pads 6 and, on the other hand, by two cavities 15a, 15b, diametrically opposite.
Les figures 1, 2, 3, 4 montrent que l'articulation du boîtier 1 comprend une surface légèrement tronconique 16 centrée sur l'axe X-X' de l'articulation dans laquelle s'emboîte une surface tronconique complémentaire 17 de l'articulation du couvercle 3.Figures 1, 2, 3, 4 show that the articulation of the housing 1 comprises a slightly frustoconical surface 16 centered on the axis XX 'of the articulation in which a surface fits additional frustoconical 17 of the articulation of the cover 3.
La partie droite de la figure 3 montre 1 ' autre articulation 18a, 18b du boîtier 1 au couvercle 3. Cette articulation comprend un ressort 19 mettant en appui les deux surfaces tronconiques complémentaires 16, 17 précitées. Un certain jeu est pratiqué entre les deux parties de cette autre articulation 18a, 18b pour permettre l'enlèvement du couvercle 3 par compression du ressort 19 et déboîtement des deux surfaces tronconiques complémentaires 16, 17.The right part of FIG. 3 shows the other articulation 18a, 18b from the housing 1 to the cover 3. This articulation comprises a spring 19 bearing the two aforementioned complementary frustoconical surfaces 16, 17. A certain play is made between the two parts of this other articulation 18a, 18b to allow the cover 3 to be removed by compression of the spring 19 and disengagement of the two complementary frustoconical surfaces 16, 17.
Par ailleurs, l'autre articulation 18a, 18b comprend deux surfaces 20, 21 en contact l'une sur l'autre sous l'action du ressort 19. L'une de ces surfaces comprend (voir figure 12) plusieurs reliefs 22 angulairement décalés engagés dans des creux 23 formés dans l'autre surface de façon à définir plusieurs positions angulaires du couvercle 3 par rapport au boîtier 1. Chaque relief 22 comprend un sommet 24, une rampe montante et une rampe descendante disposées symétriquement de part et d'autre de ce sommet.Furthermore, the other articulation 18a, 18b comprises two surfaces 20, 21 in contact with one another under the action of the spring 19. One of these surfaces comprises (see FIG. 12) several reliefs 22 angularly offset engaged in recesses 23 formed in the other surface so as to define several angular positions of the cover 3 relative to the housing 1. Each relief 22 includes a top 24, an ascending ramp and a descending ramp arranged symmetrically on either side from this summit.
Comme montré par la figure 12, les deux surfaces en contact comprennent trois reliefs 22 et trois creux 23 décalés l'un de l'autre suivant un angle de 120°.As shown in Figure 12, the two contacting surfaces include three reliefs 22 and three recesses 23 offset from each other at an angle of 120 °.
Les reliefs 22 et creux 23 coopèrent les uns avec les autres pour définir une première position dans laquelle le couvercle 3 est rabattu sur le boîtier 1 et une seconde position dans laquelle le couvercle 3 forme un angle d'environ 120° par rapport au boîtier 1.The reliefs 22 and hollow 23 cooperate with each other to define a first position in which the cover 3 is folded down on the housing 1 and a second position in which the cover 3 forms an angle of approximately 120 ° relative to the housing 1 .
Cette seconde position correspond à la position normale d'utilisation du téléphone.This second position corresponds to the normal position for using the telephone.
Par ailleurs, la position des reliefs 22 et des creux 23 est légèrement décalée (suivant un angle de 5°) par rapport à une origine correspondant à la fermeture complète du couvercle 3 pour permettre le déplacement de celui-ci vers cette position de fermeture sous l'action du ressort 19.Furthermore, the position of the reliefs 22 and the recesses 23 is slightly offset (at an angle of 5 °) relative to an origin corresponding to the complete closure of the cover 3 to allow the displacement of the latter towards this closed position under the action of the spring 19.
De plus, les deux surfaces en contact 20, 21 peuvent être déboîtées l'une de l'autre, en comprimant le ressort 19, ce qui permet de remplacer le couvercle 3.In addition, the two contact surfaces 20, 21 can be disengaged from each other, by compressing the spring 19, which makes it possible to replace the cover 3.
D'autre part, les reliefs 22 et les creux 23 coopèrent les uns avec les autres pour définir une position dans laquelle le couvercle 3 est complètement rabattu sur le boîtier 1 et où les bras de contact 5 incorporés dans l'articulation 4a n'établissent pas la liaison électrique entre le circuit électrique 2 et le microphone à la position ci-dessus et jusqu'à une première position angulaire du couvercle 3 égale par exemple à 45°. Cette liaison électrique est établie lorsque la position angulaire du couvercle 3 est située au-delà de la première position ci-dessus.On the other hand, the reliefs 22 and the recesses 23 cooperate with each other to define a position in which the cover 3 is completely folded down on the housing 1 and where the contact arms 5 incorporated in the articulation 4a do not establish not the electrical connection between the electrical circuit 2 and the microphone at the above position and up to a first angular position of the cover 3 equal for example to 45 °. This electrical connection is established when the angular position of the cover 3 is located beyond the first position above.
Les deux bras de contact 5 coopèrent avec les deux plages conductrices 6 séparées par la zone non conductrice 7.The two contact arms 5 cooperate with the two conductive pads 6 separated by the non-conductive area 7.
La position de cette zone non conductrice 7 est telle qu'au moins l'un des deux bras 5 soit en contact avec cette zone non conductrice 7 entre la position de fermeture complète du couvercle et la première position angulaire de ce dernier, indiquée ci-dessus.The position of this non-conductive area 7 is such that at least one of the two arms 5 is in contact with this non-conductive area 7 between the completely closed position of the cover and the first angular position of the latter, indicated below. above.
La figure 8 montre la position des deux bras de contact 5 lorsque le couvercle 3 est complètement fermé. L'un des bras 5 est situé entre les deux plages conductrices 6; la connexion électrique n'a pas lieu. La figure 9 montre la position des deux bras 5, après rotation du couvercle de 45°. Les deux bras 5 sont en contact avec les plages conductrices 6; la connexion électrique a lieu.FIG. 8 shows the position of the two contact arms 5 when the cover 3 is completely closed. One of the arms 5 is located between the two conductive pads 6; the electrical connection does not take place. FIG. 9 shows the position of the two arms 5, after rotation of the cover by 45 °. The two arms 5 are in contact with the conductive pads 6; the electrical connection takes place.
Les figures 10 et 11 montrent la position des deux bras 5, après rotation du couvercle de 120° et 185; dans les deux cas la connexion électrique a lieu. Bien entendu, l'invention n'est pas limitée aux exemples de réalisation que l'on vient de décrire et on peut apporter à ceux-ci de nombreuses modifications sans sortir du cadre de l'invention. Figures 10 and 11 show the position of the two arms 5, after rotation of the cover by 120 ° and 185; in both cases the electrical connection takes place. Of course, the invention is not limited to the exemplary embodiments which have just been described and numerous modifications can be made to them without departing from the scope of the invention.
